Need help to create a web site

Question

Hi..!
I need help with selecting which tool or which way to create a web page with. A web site where users can register and post ads for sale of used cars, houses, or rental of houses and sell other things like used computers, mobile phones etc..
I thought of creating a web page with asp.net and use a three-layer architecture. with presentation layer, business layer and dataacsesslayer. If I'm not mistaken there are some who call it the frontend-backend.
I was wondering if this is a correct way to create such a website with.? Are there any other ways to do it, such as MVC.? Or if there are Finished models in asp.net that one can customize for its own use like Joomla have..?
I would be grateful for any help.

Answer 1

Oops. Hit post too early. You could put some programming in the Pre-Init, too. That doesn't solve the null in the session variable, but it would fire before the page load.

Answer 2

I'm not familiar with I-frame, but some ideas that come to mind...
1. The last time I couldn't find a Session variable I was CERTAIN I had, I didn't have enable session state set to true.
2. Another thought is that it might not be set before the other event fires
3. Are you sure all the names that reference the Session variable are the same including capitol letters and exact spelling (I depend on Intellisense a LOT, so I'm forever mistyping the Session Variable names).
4. If all else fails, I would put some temporary variables and breakpoints in during debug to see when the Session Variable loses its value.

HTH

Well... there's nothing special about the code. Basically what I've done to test it is just set the menu item's NavigateURL, it's Target, and I added some text to it's Value property.

Then in the Item Cleck event I just add the Value to a Session variable. As soon as the other page loads I call the session variable to see if it actually added anything. Then the page complains about the Session Variable... "not set to an instance of an object...".

But if I try the same without the iFrame it works.


Why I want to di this:
I have a few pages in which my client's clients can fill in Details about the item they want to add to there insurance or Amend and item. The add and amend is almost the same and thus I want to try and use the same page for both. But I need to know what was clicked so that I know if the user wants to add or amend.

I hope it makes sense.

Thanks

Sounds like a coding error. You might post some relevant code so we can see what you're doing.
